dc.description.abstract | Structural, electronic and magnetic properties of the Heusler alloy Mn
2
VIn have been investigated using the density functional
theory and experimental techniques. Unlike many other Heusler compounds, Mn
2
VIn is not predicted to be half-metallic at the
optimized lattice constant, but is highly spin polarized at a slightly lo
wer lattice constant. It however exhibits ferrimagnetic coupling
between the Mn and V sublattices, as expected of Mn-based Heuslers. We have, then, synthesized the compound by arc melting and
studied magnetic properties that are of interest fundamentally and for technological applications. The structural properties were
determined using X-ray diffraction, revealing the presence of cubic and tetragonal phases in the sample. The chemical composition
was determined using energy-dispersive X-ray spectroscopy together with the scanning electron microscope, and the magnetic
properties were investigated by superconducting quantum interference device magnetometry. The alloy exhibits superparamagnetic
spin blocking with a blocking temperature
